[OPENMP] Update the diagnosis message for canonical loop form

[cchen]

Summary

The previous patch (https://reviews.llvm.org/D54441) support the
relational-op != very well for openmp canonical loop form, however,
it didn't update the diagnosis message. So this patch is simply
update the diagnosis message by adding !=, update the test
related to it, and update the section number for canonical loop
form for OpenMP 5.0 in comment.

[lebedev.ri]

Shouldn't this be OpenMP-version-dependent?
!= is only allowed in 4.5+

[lebedev.ri]

Or more specifically, why != is now silently accepted in 4.0 mode?

[ABataev]

!= form is part of OpenMP 5.0. It would be good to allow this form for OpenMP 5.0 only and emit this new error message only for OpenMP 5.0

[cchen]

Is there any way that I can find the OpenMP version in Clang? I couldn't find any example in source code. Thanks.

LangOpts.OpenMP has the version of OpenMP. For OpenMP 5.0 this value is set to 50.

[cchen]

Update the diagnosis message for canonical loop form based on OpenMP version

[lebedev.ri]

!= is still not being diagnosed in pre-5.0 mode though?

[ABataev]

What about the check for !=? it would be good to allow it only for OpenMP 5.0.
Also, add/update the tests.

You can merge these 2 messages into one using something like
"condition of OpenMP for loop must be a relational comparison ('<', '<=', '>', %select{or '>='|'>=', or '!='}0) of loop variable %1"

clang/lib/Sema/SemaOpenMP.cpp

5423

If you merge 2 messages into one, you can diagnose it this way:

SemaRef.Diag(DefaultLoc, diag::err_omp_loop_not_canonical_cond) << (SemaRef.getLangOpts().OpenMP <= 45 ? 0 : 1) << LCDecl;

[cchen]

Haven't updated the lit test for OpenMP 5.0 yet since I'm not able to check OPENMP version by using _OPENMP with preprocessor condition checking.

You don't need _OPENMP macro for this. There a lot of tests in the OpenMP directory for OpenMP 5.0 already, look for -fopenmp-version=50 option in the tests.

[cchen]

@ABataev thanks so much for your instruction, I'll look into that.

[cchen]

Update lit test for diagnose loop canonical form message for OpenMP 5.0 and
pre-5.0. Only allow fopenmp-version=50 to use "!=" as check condition in loop
canonical form.

[cchen]

"parallel_for_codegen" cannot pass now since it has two test cases for "!=" and it's hard to just add "fopenmp-version=50" since it will break lots of other test cases that have different codegen for OpenMP 5.0.
I can remove the "!=" case from "parallel_for_codegen" and add a new file such as "omp50_parallel_for_codegen" to test it but I doubt it's the right way to do it.

[lebedev.ri]

Looks about right now, thanks for unbreaking it.

clang/lib/Sema/SemaOpenMP.cpp

5419–5421

It may be much cleaner to

bool IneqCondIsCanonical = SemaRef.getLangOpts().OpenMP >= 50;

and use that

Add a new RUN directive(s) for openmp 5.0 and add a definition specific for OpenMP 5.0 run. In the code use #ifdef...endif to check that version is OpenMP 5.0 and the test with!= must be under this guard.

clang/lib/Sema/SemaOpenMP.cpp

5440–5441

Just make if(OpenMP >= 50 && opcode == BO_NE) and remove else branch

5472

else branch is not required here, the control will go to the default path with diagnostics.

[cchen]

Refactor the control flow based on the feedback, fix a failing codegen test due
to OpenMP version.

[ABataev]

LG, thanks for the fix!

[cchen]

Refactor for only load the OpenMP version number once

[cchen]

I'm not able to arc land my patch since I updated the patch for a minor refactor and the state is "not approve" now. Do I wait for the approval for the new patch so that I can arc land or I don't need to do arc land myself?
Thanks.

I would not suggest to rely on the conversion of bool values to integer, better to use IneqCondIsCanonical ? 0 : 1

[cchen]

Fix the code that rely on implicit conversion.

[ABataev]

LG

[cchen]

@ABataev, could you mark it as ready to land, please. Thanks.

I accepted it already, don't know what else I can do.

[cchen]

Oh, I was thinking that I could use "arc land" to commit my patch, but just now realize that I don't have the commit privileges. Would you please commit for me? Thanks.
